Kubva pamhosva dzinopfuura mazana maviri dzakasimbiswa pazuva mumavhiki apfuura, South Africa yakaona huwandu hwezviitiko zvitsva zvezuva nezuva kusvika kune vanopfuura zviuru zvitatu nemazana maviri Mugovera, vazhinji muGauteng.
Vachinetsekana kutsanangura kusimuka kwakangoerekana kwaitika, masayendisiti akadzidza masampuli ehutachiona uye akawana musiyano mutsva.Iye zvino, inosvika makumi mapfumbamwe muzana emhosva nyowani muGauteng inokonzerwa nazvo, sekureva kwaTulio de Oliveira, director weKwaZulu-Natal Research Innovation uye Sequencing Platform.

NEI MASAYENDISITI ACHINEMHEDZA NENYAYA ITSVA IYI?
Mushure mekudaidza boka renyanzvi kuti vaongorore data, WHO yakati "umbowo hwekutanga hunoratidza njodzi yakawedzera yekutapukirwazve nemusiyano uyu," kana zvichienzaniswa nezvimwe zvakasiyana.
Izvi zvinoreva kuti vanhu vakaita chibvumirano cheCCIDID-19 uye vakapora vanogona kubatwa zvakare.
Musiyano uyu unoratidzika kunge uine huwandu hwakanyanya hwekuchinja - angangoita makumi matatu - muconavirus 'spike protein, iyo inogona kukanganisa kupararira kwayo kune vanhu nyore.
Sharon Peacock, akatungamira genetic kutevedzana kweCCIDID-19 kuBritain kuYunivhesiti yeCambridge, akati dhata kusvika parizvino rinoratidza kuti shanduko nyowani ine shanduko "inofambirana nekuwedzera kutapurirana," asi akati "kukosha kwekuchinja kwakawanda ndiko. hazvisati zvazivikanwa.”
Lawrence Young, chiremba wehutachiona paYunivhesiti yeWarwick, akatsanangura omicron se "yakanyanya kuchinjika vhezheni yehutachiona yatakaona," kusanganisira shanduko inogona kunetsa isati yamboonekwa yese muhutachiona humwe.

CHII CHINOZIVIKANWA UYE CHISINGAZIVIKANWI PAMUSORO PEKUSIYANA?
Masayendisiti anoziva kuti omicron ine genetic yakasiyana kubva kune zvakambosiyana zvinosanganisira beta uye delta musiyano, asi havazive kana shanduko idzi dzemajini dzichiita kuti iwedzere kutapurirana kana njodzi.Parizvino, hapana chinoratidza kuti musiyano unokonzera chirwere chakanyanya.
Zvinogona kutora mavhiki kugadzirisa kana omicron ichinyanya kutapukira uye kana majekiseni achiri kushanda pairi.
Peter Openshaw, purofesa wezvemushonga wekuyedza paImperial College London akati "hazvigoneke zvakanyanya" kuti majekiseni aripo haashande, achiona kuti anoshanda pakurwisa mamwe akawanda akasiyana.
Kunyangwe dzimwe shanduko dzemajini muomicron dzichiita sekunetsekana, hazvisati zvanyatsojeka kana dzichizoisa hutano hweveruzhinji njodzi.Mimwe misiyano yapfuura, senge beta mutsauko, pakutanga yakavhundutsa masayendisiti asi haina kupedzisira yapararira kure.
"Hatizive kana mutsauko mutsva uyu ungabata nzvimbo munzvimbo dzine delta," akadaro Peacock weYunivhesiti yeCambridge."Vatongi vari kunze kuti mutsauko uyu uchaita sei kune mamwe mavhesi ari kutenderera."
Kusvika pari zvino, delta ndiyo yakanyanya kurongeka fomu yeCCIDID-19, inodarika makumi mapfumbamwe nepfumbamwe muzana yemateedzana akaendeswa kune dhatabhesi huru yepasirese.

IYI NYAYA ITSVA YAKUKA SEI?
Iyo coronavirus inoshanduka sezvainopararira uye akawanda matsva akasiyana, kusanganisira ayo ane kunetsekana kwemajini shanduko, kazhinji anongofa.Masayendisiti anotarisisa COVID-19 kutevedzana kwekuchinja kunogona kuita kuti chirwere chiwedzere kutapurirana kana kuuraya, asi havagone kuona izvo nekungotarisa hutachiona.
Peacock akati musiyano uyu "unogona kunge wakavapo mumunhu ane hutachiona asi akatadza kubvisa hutachiona, zvichipa hutachiona mukana wekushanduka," mumamiriro ezvinhu akafanana nemafungiro enyanzvi musiyano wealpha - wakatanga kuzivikanwa muEngland - yakabudawo, nekuchinja-chinja mumunhu ane immune-compromised.
ZVIRAMBISO ZVEKUFAMBA ZVIRI KUITWA NEDZIMWE NYIKA ZVINORURAMA HERE?
Pamwe.
Israel iri kurambidza vatorwa kupinda mudunhu uye Morocco yakamisa nzendo dzese dziri kuuya dzekunze.
Dzimwe nyika dzinoverengeka dziri kurambidza kufamba nendege kubva kumaodzanyemba kweAfrica.
Nekuda kwekukurumidza kusimuka kweCCIDID-19 muSouth Africa, kurambidza kufamba kubva mudunhu "hungwaru" uye kunotenga zviremera nguva yakawanda, akadaro Neil Ferguson, nyanzvi yezvirwere zvinotapukira kuImperial College London.
Asi WHO yakaona kuti zvirambidzo zvakadaro zvinowanzoganhurwa mukuita kwavo uye yakakurudzira nyika kuti dzichengete miganhu yakavhurika.
Jeffrey Barrett, director weCCIDID-19 Genetics kuWellcome Sanger Institute, akafunga kuti kutanga kuonekwa kwemutsauko mutsva kunogona kureva kuti zvirambidzo zvatorwa zvino zvingave nemhedzisiro yakakura kupfuura pakatanga kubuda delta.
"Ne delta, zvakatora mavhiki mazhinji muIndia yakashata isati yave pachena kuti chii chiri kuitika uye delta yakanga yatozvidyara munzvimbo dzakawanda pasirese uye yakanga yanyanya kunonoka kuita chero chinhu nezvazvo," akadaro."Tinogona kunge tave pane imwe nguva neiyi mutsauko mutsva saka panogona kunge pachine nguva yekuita chimwe chinhu nezvazvo."
Hurumende yeSouth Africa yakati nyika iri kubatwa zvisina tsarukano nekuti ine genomic sequencing uye inogona kuona musiyano nekukurumidza uye yakakumbira dzimwe nyika kuti dzitarise kurambidzwa kufamba.
